IMPROVEMENT lN MACHINESIFOR COMPRESSING MUSKET-BALLS.

l Specication forming part of Letters Patent No. 34,844, dated April 1,1862.

that the following is a full, clear, and exact" description of my saidinvention, reference being had to the annexed drawings, making part ofthis speciiication, wherein- Figure l is a plan of my machine complete.Fig. 2 is a vertical section of the dies for making round balls. Fig. 3is a vertical sect-ion as open, and FigA is a section as closed, (inlarger' size,) of the dies for making Mini or hollow balls.

Similar' marks of reference denote the saine parts.

The nature of my said invention consists in an arrangement of dies forcompressing and delivering balls either globular, elongated, or hollow,said balls being made from short sections of lead or suitable metal outoif from a bar and presented successively to the action of the dies.

In the drawings, a is a frame of suitable construction carrying thecrossshaft h, propelled by competent power.

c is a sliding die-stock sustained in the bearings d d, andreciprocated. by the crank e and connection f.

g is a connectingerod from. a pin e at the end of b to an adjustable pinl in a slotted arm h, that acts as a lever and moves on the shaft 2 ofthe ratchet-wheel t', which wheel z' is moved by the pawl t" therequired amount each reciprocation of the rod g. On the shaft 2 is agear-wheel 7c, corresponding to and working into the wheel k on theshaft 8. (See Figs. l and G.) These two shafts 2 and 3 are in bearingsk2 and fitted each at the outer end with a grooved feed-roller Z, and Zis a screw by which the said rollers are pressed together and upon a baror strip of lead. m with the necessary power to feed it into the machinewhen said rollers are moved by the wheel t' and pawl t. The lead passesthrough a hole in a die n, and is stopped when projecting the necessarylength by an adjustable gage n, and is cut off by the cutter o, that isbrought up at the proper time by the cam p and lever p. At the sainetime a holdingjaw q comes up by the spring t, or is pressed up by thelevcr g and cam q2, so as to sustain the section of lead 5 as cut offand while being carried to the line of the die fr in the stock c, and sosoon as taken by said die the cutter o and the holding-jaw q retire orare forced out of the way by their respective cams.

The dies fr and s which form the ball are to be of the size and shaperequired. I have shown the same in Figs. l and 2 as hemisphericalcavities in order to make a globular ball. Of course the dies must beaccurately iitted and adjusted, and in order to throw out the ball asthe dies part I make use of the delivering-punches 6 and 7, set in holesin the respective dies and actuated by levers 8 and 9, that areconnected together at r and s come together may be removed in arevolving box or rumbler.

' In order to form the hollow or Mini balls in my machine, I employ thedies shown in Figs. 3, 4, and 5, wherein the die fr is formed with aconical end to produce the cavity in the ball, and the fixed die s isshaped to form the point of the ball with the pushing or delivery punch6, as before. It is generally necessary, however, to form grooves aroundthe ball near the base, and to provide for such grooves I make a dividedface to the die, as at r2 r3, and these pieces are to slide in groovescrosswise of the die 8'; and to give the motion required for opening andclosing these face-pieces I employ the wedgeszf t', projecting from thedie r or die-stock c, so that as this die moves forward to compress thelead the facepieces r2 r3 are closed and firmly held by the wedge-barsttwhile the ball is formed, and then these face-pieces are opened forthe delivery of the ball by the reverse movement, the inclined parts t ttaking offsets in the slots through which they move to effect thisopening for the delivery of the ball. If the pointed end of the die r'came in contact with the lead blank without being accurately guided, thesaid point once entering the lead eccentric of said cylindrical blank orsection of the lead bar, the ball would be irregular. I thereforeprovide the sliding cylinder u around the pointed die r', which,receiving the lead blank as presented to the dies, conveys the same intothe die s', when the end of this cylinder, coming in contact with theface-pieces r2 r3, is ar-A rested and the compression is effected by thedie r sliding through this cylinder u, the spring u allowing for thismovement,` and as the dies withdraw this cylinder being slid forward byits springu insures the delivery of the ball from the pointed die r; andto the said cylinder u I communicate a slight turning motion by means ofthe spring u',

the ends of said spring being attached, re-

spectively, to the stock c and cylinder u, and the spring wound up inthe act of being put in place. Hence this spring keeps the cylinder andwedge-shaped incline (shown by dotted lines) toward 'each other, and asthe die r draws back, the pressure of the shoulders @c of said die fr"being removed, the said springu causes the cylinder to partially turn,andthe en d thereof, being properly shaped, acts against the edges ofthe die-faces r2 r3 and cuts off any thin burr of lead that may beprojecting, or separates it so nearly that it will fall off as the ballis handled. This same operation might be effected by the holdingturnedin their surface surrounding and a slight distance from the ball, inorder that a cylindrical ring projecting from and moving with the die umight enter said groove to hold the face-pieces more rmly together.

A cylinder similar to the cylinder u might be. applied to the die r forforming globular balls, to guide the blank 5, and separate any slightburr, the same as with the Mini ball.

What l claim, and desire to secure by Letters Patent, is

1. YThe delivery-punches 6 and 7, adjusted by means of the levers 8 and9 and set-screws 11 and 12, in combination with the dies r and s,arranged substantially as set forth. Y

2. In combination with the said dies rf and s, provided with thedelivery-punches, levers, and adjusting-screws aforesaid, the holdingjawq and cutter 0, arranged as and for the purposes set forth. g

3. The solid die s and r'sliding face-pieces r2 r3, constructed andacting as and for the purposes spe'cied. p

4. The cylinder u as constructed, having a partially-revolving movementaround the die r, in combination with the spiral spring u', as setforth.

5. The arrangement of the dies s r r2 'r3 and Wedge-bars t t, acting inthe manner and for the purposes set forth.

Inwitness whereof Ihave hereunto setlniy Y 'signature this 12th day ofDecember, 1861.
